L'amour propre ne le reste jamais très longtemps(1985)

In a routine sex farce, Gautier (Jean-Claude Dauphin) is a man determined to figure out how to give a woman an orgasm -- which of course requires a lot of practice and experimentation. His buddy Roussel (Jean-Luc Bideau) also chases after women but does not share Gautier's unique quest. Rose (Nathalie Nell) finds Gautier entrancing and devises a way to capture his heart while helping him on his search for the ultimate turn-on.
